GeForce GTX 560 Ti review -
Specifications and Features

Aah yes, yet another GPU to review! So today I wanted to keep things nice and simple. The GeForce GTX 560 Ti is in fact the GF104 GPU, it is refreshed and tweaked a little to allow higher clock speeds with presumably a lower power draw. The GeForce GTX 560 Ti has 384 Shader processor cores, 32 ROPs, and a 256-bit wide memory interface that connects to four 64-bit controllers with each 256MB memory tied to it, so that's 1 GB of memory for the product released today.

The new GPU has holstered a rather high GPU clock speeds, with 822 MHz core, 1644 MHz on the shader cores, and 4000 MHz (GDDR5 effective datarate) memory, chunking out a very decent 128 GB/s in memory bandwidth.

Now most of all this sounds familiar eh?, yeah... remember the GF104 being used in the GeForce GTX 460 series? The new GF114 is in fact the basis of that IC, yet now with all shader processors enabled.

For the bigger part of the specifications the two feel similar when it comes to shader processor count, memory bus and clock frequencies, the GTX 560 Ti definitely will be a good chunk faster and as you'll learn a heck of an overclocker.

If you look closely at the SM (Streaming Multiprocessor) partitions, then you can see and calculate that the 336 Shader processors based GF104 on the GeForce GTX 460 has in fact seven SM partitions. 7 are enabled = 336 Shader processors. The GF114 GPU has 384 shader processors, and has that last available SM cluster enabled.

Okay so the GeForce GTX 560 Ti is still based on a 40nm fabrication node, still has 1.95 Billion transistors and thus looks and feels like the GTX 460, yet now with 48 shader processors and accompanying PolyMorph Engine added, an extra 8 Texture units and sure, much faster clock frequencies. So is the GF114 in fact a GF104 ? Yep, it sure is.

All cards deriving and based on this GPU will be based on a dual or even triple-slot cooling design based on what the AIB/AIC partners prefer and come with two dual-link DVI and a mini-HDMI connector. HDMI will again pass sound through, including bit streaming support for Dolby True HD and DTS-HD Master. Being a mid-range product, only 2-way SLI will be allowed and thus you'll only see a single SLI finger/connector on the PCBs. Okay, the next stop will be an extensive photo-shoot of today's product.
